PCI: add PCI-X/PCI-Express read control interfaces

This patch introduces an interface to read and write PCI-X / PCI-Express
maximum read byte count values from PCI config space. There is a second
function that returns the maximum _designed_ read byte count, which marks the
maximum value for a device, since some drivers try to set MMRBC to the
highest allowed value and rely on such a function.
